To all whom it. may concern;

Be it known that LALFRED \V. NUNN, a subject of Edward VII, King of Great Britain, residing in Cambridge, in the county of MiddleseX and State of Massachusetts, have invented a new and useful Improvement in Spools for Use with Automatically-Playing Musical Instruments, of whichthe following is a full, clear, and exact description, referxo ence being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

My invention is designed especially for use in that class of instruments in which a strip of perforated paper or the like is used to ad mit air to suitable passages to operate reeds or to cause the operation of strikers to en gage the keys of a musical instrument. The strips often vary somewhat in width, and it is there fore desirable that the'roll or spool shall be adjustable in length in order to serve not only as a roll on which the paperis to be wound, but also as a guide to cause the paper to be wound straight and smooth'thereon.

My inventionwill be understood by reference to the drawings, in which Figure 1 is an elevation, partly in-longitudinal section, of a spool embodying my invention, 2 being a cross-section on line 2 2 of Fig. 1.

A is the spindle, which may be provided with a pin a at each end to engage in suitable bearings in the machine. Upon each end of the spindle is slidably mounted a sleeve A,

3 5 having at its outer end a projecting portion or flange A, which serves as a guide for the edge of the paper. Each sleeve is slotted, as' indicated at a, and the spindle is provided at each end with a pin aiwhich passes up through 40 the slot, thus allowing each sleeve A to slide lengthwise of the spindle, but requiring it to be turned therewith.

As it is desirable that when once set in place each sleeve shall remain there fixed, some 5 form of resilient device should be interposed between the spindle and the sleeve, so that the sleeve shall not be moved without the exercise of some little force. The form of resilient device which appears to me best for this purpose is shown in the drawings, where B B represent recesses inthe spindle, each recess being provided with a frictional spring lying partly therein. The end I) of each spring is fast to the spindle,and the end I) is free to yield somewhat when required to do so by the movement of the sleeve. The middle section b of each spring normally projects somewhat from the surface of the spindle, so that as the sleeve is slipped over it it is compressed and binds against the sleeve with considerable stress, and thus holds the sleeve against any ordinary strain;

It will be seen that the two sleeves form, in fact, a tubular roll, which is supported upon the spindle and which is adjustable in length, and upon which the paper strip may not only be wound, but may be guided by means of the flanges A, and it is also evident that such a roll will have other uses than that for which it is immediately intended.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination of a spindle adapted to be rotated, flanged sleeves mounted thereon, one or both of which sleeves may slide on the spindle so that their flanged ends may have an adjustable relation to each other, and a resilient member interposed between the sliding sleeve and the spindle so as to hold the sleeve at any degree of adjusted position.

2. The combinationof a spindle adapted to be rotated, flanged sleeves mounted to slide thereon so as to be adjustable in their relative positions one to theoth'er, a resilient member interposed between each sliding sleeve and the spindle so as to hold the sleeve at any degree of adjusted position.

3. The combination of a spindle adapted to be rotated, flanged sleeves mounted to slide thereon so as to be adjustable in their relative positions one to the other, a resilient member interposed between each sliding sleeve and the spindle so as to hold the sleeve at any degree of adjusted position, and means for preventing the sleeves and spindle rotating independently of one another, substantially as described.

4. The combination of a spindle adapted to be rotated, flanged sleeves mounted to slide thereon so as to be adjustable in their relative positions to one another, a spring interposed between each of said sleeves and the spindle for retarding the sliding movement of said sleeve relatively to said spindle and so for holding the sleeve at any degree of adjusted position, and pins extending radially from I 5 said spindle and extending into a slot out in each corresponding" sleeve to prevent the same from turning independently of the spindle, substantially as described.
